At a putt putt course there are 50 yellow golf balls, 45 red golf balls, and 65 blue golf balls. What ratio compares the number

oksian1 [2.3K]

Blue balls : Total number.

Total number of balls = 50 + 45 + 65 = 160

Blue balls : Total number.

= 65: 160 Divide both by 5.
= 13 : 32

= 13/32. That is the ratio.

g If there are 52 cards in a deck with four suits (hearts, clubs, diamonds, and spades), how many ways can you select 5 diamonds

dezoksy [38]

Answer:

The number of ways to select 5 diamonds and 3 clubs is 368,082.

Step-by-step explanation:

In a standard deck of 52 cards there are 4 suits each consisting of 13 cards.

Compute the probability of selecting 5 diamonds and 3 clubs as follows:

The number of ways of selecting 0 cards from 13 hearts is:

${13\choose 0}=\frac{13!}{0!\times(13-0)!} =\frac{13!}{13!}=1$

The number of ways of selecting 3 cards from 13 clubs is:

${13\choose 3}=\frac{13!}{3!\times(13-3)!} =\frac{13!}{13!\times10!}=286$

The number of ways of selecting 5 cards from 13 diamonds is:

${13\choose 5}=\frac{13!}{5!\times(13-5)!} =\frac{13!}{13!\times8!}=1287$

The number of ways of selecting 0 cards from 13 spades is:

${13\choose 0}=\frac{13!}{0!\times(13-0)!} =\frac{13!}{13!}=1$

Compute the number of ways to select 5 diamonds and 3 clubs as:

${13\choose0}\times{13\choose3}\times{13\choose5}\times{13\choose0} = 1\times286\times1287\times1=368082$

Thus, the number of ways to select 5 diamonds and 3 clubs is 368,082.

Dots sells T-shirts ($3) and shorts ($7). In April, total sales were $520. People bought 2 times as many T-shirts as shorts. How

timofeeve [1]

Let's assume

number of shorts is x

we are given

People bought 2 times as many T-shirts as shorts

so, number of T-shirts is 2*x=2x

Dots sells T-shirts ($3) and shorts ($7)

so, total price of T-shirts $=3*2x$

so, total price of shorts $=7x$

now, we are given

total sales were $520

so,

total price of T-shirts+total price of shorts = total sales

we will get equation

$3*2x+7x=520$

now, we can solve for x

$13x=520$

$x=40$

so,

number of shorts is 40

number of T-shirts is 2*40=80............Answer
